well, I don't know too much, but their latest album has no name but is usually printed as two empty parentheses...( ) and has no writing on it, no track titles, lyrics, liner notes, except "SIGUR ROS". the sung "lyrics" on the album are a misxture of English and Icelandic sounds and don't make real words, so you can kind of mushmouth along with whatever you want (that's the intent, I hear).
